Abstract
The utility model discloses an air intake mechanism for an inflator, which is composed of a transition rod arranged at the end of a push rod, a sealing gasket arranged at the connection of the transition rod and the push rod, and an air slot arranged on the transition rod along the axial direction. The transition rod is simultaneous used for installing a piston, and the length of the transition rod is lightly larger than the installation thickness of the piston. As the utility model uses the air slot arranged on the transition rod to substitute an air inlet and the sealing gasket to substitute a sealing air inlet on a conical surface on the push rod, the utility model has the advantages of simple structure, easy fabrication, and reliable operation. Even if the air intake mechanism for an inflator is damaged, the air intake mechanism for an inflator is easy to repair or remove and replace.
Description
The utility model relates to the improvement of pump, relates in particular to the improvement of pump admission gear.
Pump can be inflated for vollyball, football, bicycle tyre etc., so that they can use, also can be used as the air-inflating device on the sprayer, and its application is very widely.The admission gear of existing pump is the bulge loop of installing by the garden conical surface of push rod end, near this end, the bounding means that cooperates with this bulge loop and constitute with the inlet hole of said garden cone match.When mentioning push rod, because the effect of bulge loop and bounding means makes the garden conical surface of push rod end leave inlet hole, the piston of pump is raised, air enters in the cylinder by inlet hole; When pressing down push rod, the garden conical surface of its end has been sealed inlet hole, and the air in the cylinder is compressed under the effect of piston.Because the garden conical surface required precision of push rod end is higher, otherwise can't be sealed into pore, so difficulty of processing is bigger, also be difficult to repair.Therefore many pumps are scrapped.
The purpose of this utility model provides a kind of admission gear of pump, and its manufacturing is easy, use is reliable, be easy to reparation.Can greatly prolong the working life of pump.
The purpose of this utility model is achieved in that the admission gear of pump, and it is made of the transiting rod that is installed in the push rod end, the sealing gasket that is installed in push rod and transiting rod junction point, the air drain of opening on transiting rod vertically.
The utility model will be further described below in conjunction with accompanying drawing.Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the A-A sectional view among Fig. 1.
According to Fig. 1, push rod 1 end is equipped with transiting rod 6, and transiting rod 6 has air drain 5 vertically, at the junction point of push rod 1 and transiting rod 6 sealing gasket 4 is installed, and piston 2 is installed on the transiting rod 6, and the length of transiting rod 6 should be slightly larger than the installation thickness of piston 2.The 3rd, the cylinder of pump.
When mentioning push rod 1, sealing gasket 4 separates with piston 2, and along with piston 2 moves upward, the air drain 5 of air on transiting rod 6 enters cylinder 3; When pressing down push rod, sealing gasket 4 moves downward, and has sealed air drain 5, cylinder 3 interior air can not be run spill.
The utility model is simple in structure, owing to replaced inlet hole with the air drain of opening on transiting rod, seals the suction port of air drain with sealing gasket, so makes easily, uses reliable.Even damaged, also very easily repair or change.Greatly prolonged the working life of pump.
Claims (1)
1, the admission gear of pump, it is characterized in that being constituted by the transiting rod that is installed in the push rod end, the sealing gasket that is installed in transiting rod and push rod junction point, the air drain of opening on transiting rod vertically, transiting rod is used to install piston simultaneously, and its length is slightly larger than the installation thickness of piston.
